Abstract: PROBLEM TO BE SOLVED: To reduce the number of detected part (a projection part and a tooth) in an outer periphery of a cam shaft while judging a cylinder per stroke phase difference between cylinders by arranging a cylinder judging means formed in such a constitution that generation of a cam signal is detected by angle detected by an angle region detecting means, and the cylinder is judged on the basis of its result. SOLUTION: For example, an angle region of 180 deg. CA just after a reference signal REF outputted just before a compression top dead conter TDC of a #4 cylinder, is detected dividing into two angle regions of the first half part of 0 deg. CA to 90 deg. CA and the second half part of 90 deg. CA to 180 deg. CA, and it is judged whether a cam signal CAM is generated by each angle region or not. The cam signal generation is divided into four patterns, that is, only in the first half part, only in the second half, in both parts and none of both parts, and the cylinder is judged by which pattern it corresponds to. To say concretely, the cylinder is judged on the basis of a signal from a crank angle sensor and a cam sensor, and a reference signal REF generated artificially.

IPC: H04N1/411
Filed: 1984-06-08
Abstract: PURPOSE:To shorten the transmission time by thinning out picture elements in the same positions of individual lines in the proportion of one to plural picture elements and combining two- dimensional decoding to generate picture information having the volume of information before picking-out of picture elements on the basis of decoded picture information. CONSTITUTION:An original is scanned by a reading part 9 to read it as a black-and-white binary signal, and a picking-out part 10 thins out picture elements in the ame positions of individual lines in the main scanning direction in the proportion of one to n numbers of picture elements. The signal encoded by an MR.MMR encoding part 11 is transmitted by a transmitting part 12; and in the reception side, the transmitted signal is received by a transmitting part 13 and is decoded by an MR.MMR decoding part 14, and thinned-out picture elements are forecasted and interpolated by an interpolating part 15, and the result is stored as a hard copy by a recording part 16. The picking-out part 10 is so constituted that picture elements are thinned out in the proportion of one to, for example, three, and the input of a main scanning synchronizing signal (a) is received to generate a synchronizing signal for the picture element to be thinned out by a ternary counter 17, and a signal (e) where picture elements of an picture information input (b) are thinned out is outputted by a shift register 18. Thus, the degradation of the picture quality is relatively small, and the transmission time is shortened considerably.

Title: Image forming device
Inventor: HISHIKAWA TAKAHIDE
IPC: G03G15/20
Filed: 1989-05-15
Abstract: PURPOSE:To improve fixation efficiency and durability by reversing a fixing roller before its fixing operation. CONSTITUTION:An oscillatory gear 13 is selected in forward rotation and a driving force is transmitted in backward rotation to a gear by an oscillator gear 14. The gear 15 is coupled with a motor and when a solenoid 17 draws a plate material 19 rotatable around the shaft 18 of a gear 16 in the backward rotation, the gears 13, 14, and 20 move to positions shown by alternate long and two short dashes lines and the gear 14 engages the gear 12 to enable reverse driving. The fixing roller which is driven to reverse slightly starts forward rotation by releasing the solenoid 17, moving the plate material 19, and making the gear train reaches solid-line positions. Thus, the fixing roller is reversed temporarily before the fixing roller starts fixing operation to prevent the fixing roller and a pressure roller from being contaminated with toner deposited on a developer peeling and removing member, thereby performing the fixation without staining a recording material which carries an unfixed toner image.

Title: Video amplifier
Inventor: SASE TAKASHI
IPC: G09G1/06
Filed: 1989-05-15
Abstract: PURPOSE:To reduce the power consumption with a two-phase current output by outputting a complementary current from a gain controller. CONSTITUTION:A transistor (TR) Q2 is put in operation so as to raise the voltage at a voltage output terminal 7. The currents of current amplifiers 40 - 60 decrease, and the IR voltage drop across a resistance R2 becomes small to raise the emitter voltage of a TR Q2, so the voltage at the terminal 7 rises. The current of a current amplifier 30 increases because it is in opposite phase and the IR voltage drop across a resistance R3 becomes large to lower the emitter voltage of a TR Q1, so that the current of the TR Q1 is decreased by the resistance R1. A large current is required to raise the voltage at the terminal 7 and no current is required to lower the voltage, so push-pull operation is performed with a small current and the power consumption is reducible.

Title: Optical communication system
Inventor: ASAMURA SEIICHI
IPC: H04B10/2507
Filed: 1986-05-23
Abstract: PURPOSE:To use light sources having a same oscillation wavelength and to perform multiplex communication by using light sources having the same oscillation wavelength for optical communication using one optical fiber and assigning narrow spectrum bands included in the oscillation spectrum width of light sources to two optical signals independently of each other. CONSTITUTION:Channels based on light sources 1 and 8 are defined as ch1 and ch2. Both light sources 1LAMBDA0 and 8 oscillate the light with a center wavelength lm and a spectrum width W. Loss wavelength characteristics of optical directional couplers 2 and 6 to the channel ch1 are equal to each other, and a pass band and a stop band are alternatively repeated at a wavelength period W/N with respect to the spectrum width W of light sources 1 and 8. Loss wavelength characteristics of couplers 2 and 6 to the channel ch2 are equal to each other and are opposite to those to the channel ch1. Therefore, pass bands and stop bands of channels ch1 and ch2 coincide with each other respectively. Consequently, the output light of the light source 1 which passes the optical directional coupler 2 is reflected on optical connectors 3 and 5 but does not reach a photodetector 9 because its spectrum coincides with the stop band of the second channel. The output light of the light source 8 does not reach a photodetector 7 similarly. The output light of the light source 1 reaches the photodetector 7, and that of the light source 8 reaches the photodetector 9 similarly.

Abstract: PURPOSE:To improve the extent of groundability in a tire, by installing two types of pistons in a suspension cylinder, while moving the piston on one side with operation of a selector valve and thereby adjusting a stroke rate of the piston on the other, and changing the maximum rockable angle of a wheel shaft. CONSTITUTION:In case of running on the ground having large uneven undulations, the maximum rockable angle of a wheel shaft 6 is changed into extension. That is to say, a selector switch 22 is operated to a (a) position and a shutoff valve 17 is selected to a (c) position. And, a selector valve 31 is operated to a (f) position, and oil in each second piston oil chamber 30 of symmetrical culinders 12 is opened to an oil tank 21 through respective oil passages 38, 39 and 40, thus each second piston 28 is made into freedom. At this time, since the wheel shaft 6 is rocked centering on a center pin 11 of an equalizer 9, a clearance between the top of a first piston 27 and the underside of a stepped part 26 in a cylinder tube comes to 2X(S1+S2), so that the maxi mum rockable angle is thus expanded.
